Iranian Investigators: Ukrainian Plane on Fire Before Crash VOA News Iranian investigators said Thursday the crew of a Ukrainian passenger jet that crashed shortly after taking off from Tehran's airport had tried to turn back, and that the pilot made no radio communications about any problems. The initial report from Iran's Civil Aviation Organization also cited witnesses on the ground and in a passing aircraft as saying the Ukraine International Airlines plane was on fire before it hit the ground. .
